PROVIDING CLOUD-BASED SERVICES USING DYNAMIC NETWORK VIRTUALIZATION

摘要

The invention is directed to providing cloud-based services using dynamic network virtualization. Embodiments of the invention provide a cloud-based service over a system that has a dynamic network virtualization architecture. The architecture includes a set of distributed forwarding elements with centralized control, and at least one virtual machine that is bound to one of the forwarding elements. These features enable the virtual machine to be migrated across a wide area network while maintaining its original IP address and service continuity.

主权项

1. A method of providing a cloud-based service over a packet switching network via a system having a dynamic network virtualization architecture comprising a plurality of forwarding elements controlled by a central controller and a plurality of virtual machines, each said machine being associated with one of the forwarding elements, the method comprising:
receiving, at a first forwarding element, a data packet of said service; determining, by the first forwarding element, a destination of the data packet; forwarding, responsive to said destination being a virtual machine associated with the first forwarding element, the data packet directly to the virtual machine; receiving the data packet at the destination; and processing the data packet by the destination in accordance with said service.
